Choosing among TVs & display panels means settling one immediate tension: does a larger Samsung OLED justify the higher outlay, or is the smaller LG OLED the better fit? For a home theater TV, room scale and connection needs matter as much as resolution. Samsung leans toward screen size, broader inputs, and Vision AI; LG emphasizes a lower price with 4K HDR, Wi-Fi, and voice search.
Quick verdict
The Samsung S90F is the stronger match for a larger room or a setup using several kinds of equipment. Its OLED display, 2160p (4K) resolution, broader connection range, Game Mode, and AI-enhanced picture and sound create a feature-rich brief. The open-box condition and higher price are the tradeoffs.
The LG B4 is the better fit when keeping the initial outlay lower is the priority. It combines OLED and 4K HDR with Wi-Fi Ready, Voice Search, a remote control, Picture in Picture, and Sports Mode. Its used condition and shorter input list give it a different use case.

Product notes
Samsung S90F OLED
Samsung S90F OLED is the choice for the larger-screen brief while retaining 2160p (4K) resolution and OLED display technology. Vision AI appears in the model name, and the feature set adds AI-enhanced picture and sound, AI-based 4K upscaling, OLED HDR+, Built-in SmartThings Hub, and Gaming Hub. Motion Xcelerator 144Hz and Game Mode further define its feature mix. The connection range spans Bluetooth, coaxial F, digital optical, Ethernet, HDMI, and USB, which gives it a clear fit for a home theater with varied source types. The limitation is concrete: its condition is open box, and the listed price is USD 989.00. Choose it when screen scale, connection variety, and AI-focused functions take priority.
LG B4 OLED
LG B4 OLED suits a shopper seeking a smaller-screen smart TV with HDR. It combines 2160p (4K) resolution and OLED display technology with Wi-Fi Ready, Voice Search, Remote Control Included, Wide View Angle, and HDR TV. Picture in Picture, Sports Mode, and a 2 Port USB Hub give it a distinct feature mix for multitasking and sports-focused use. Its limitations are the used condition and the narrower connection selection of HDMI plus Digital Audio Optical TOSLINK. It is a less suitable match for someone who specifically needs Bluetooth, Ethernet, USB, or coaxial F inputs. Choose LG when those particular features cover your setup and its lower price is the deciding factor.
Final choice by use case
- For a larger home theater: Choose Samsung S90F for its larger OLED screen, Vision AI, Gaming Hub, and broader input range.
- For a lower upfront price: Choose LG B4 for its lower listed price and focused mix of Wi-Fi, voice search, HDR, Picture in Picture, and Sports Mode.
- For varied wired and legacy connections: Samsung S90F is the clearer match because its connection list includes coaxial F, Ethernet, USB, Bluetooth, HDMI, and optical inputs.
- For the simplest final decision: Pick Samsung if screen scale and connection breadth justify the open-box condition. Pick LG if the lower price matters more and HDMI plus optical cover your setup.
